450 x 19

A 4.50 x 19 cross (bias) ply tyre with a period correct triple-stud pattern designed by Blockley. This incredible quality tyre has dimensions with the correct overall tread width, overall width and diameter. Importantly our 450x19 tyre can also fit the narrower original specification wheel rims correctly - as well as resulting in great handling and ride qualities. This perfect product is not a multisize dual marked tyre!

A popular vintage tyre size, except that 450 x 19 was never made in the vintage period!  The original size was (27 x 4.40) later called 4.40x19, so the dimensions of the Blockley tyre take this into account. There is nothing made in the world today that is as good, or as authentic looking as this 450x19 Blockley triple stud tyre that we painstakingly designed in-house, that many have since tried to copy. This 450x19 tyre size is a popular fitment for many cars of the 1920's and 1930's such as Riley 9, Bugatti (Types 37 & 40), Frazer-Nash etc, and like many of the other Blockley cross-ply tyres we produce, these are not a compromised dual marked tyre with bulbous sidewalls or a chunky tread pattern that this size never had. All our Blockley tyres are a 100% road tyre with sidewalls that would survive being curbed, but many people also choose to compete with also. 

All Blockley Cross (Bias) ply tyres are made to fit the original rim widths, something other manufacturers have forgotten about over time. We made this tyre to fit a 2.75" wheel rim width, and it can be fitted to a rim as small as 2.25" - see details below. In addition they are genuine tyres for road use, with a robust sidewall and covering, capable of being 'curbed' as you would expect from a tyre suitable for road use. The Dunlop triple stud pattern in period was a problematic one with the treads wearing unevenly, which resulted in it being superseded. We liked the period look of the triple stud tyre, so we re-designed all features of this pattern to make it not only work correctly but without wearing out in no time. The compounding of all our cross (Bias) ply tyres conform to FIA Appendix K which uses Dunlop 204 compound as its reference hardness. This same Blockley tyre, surprisingly, has no equal having won many thousands of races and other competitions as well as Concours d'Elegance events, including class wins and overall best of show at Pebble Beach!

This is why we coined the term Road Race for tyres when we started. Which has been copied (as have many of our tyres) by the classic tyre wholesalers who Blockley do not sell through. So beware of over priced imitations!

All Blockley tyres are made with new moulds and tooling and with the highest level of quality control, resulting in a product of unsurpassed quality, roundness and conformity.
